38 LC is an earlier cartridge. When they wanted the proverbial "more power" they lengthened it and called it the 38 SPECIAL...... which later was lengthened and hotted-up again to make 357 Magnum.
297/250 Rook and Rabbit can be made by reforming with FL die and thinning the rim of 22 Hornet brass, same as 297/230.
Finally! A sort-of use for those 25ACP dies you got such a great price on at the gun show!
George, I have couple LC's... yes you can put a 38 special into the bored through one... but it doesn't fit an LC properly. The diameter at the base is smaller on 38 Special shells. And who actually has a original to check.
